[Role of rams in the epizootiology of salmonellal abortion in sheep].

Studied was the susceptibility of rams to a Salmonella abortus ovis infection. It was found that the animals could resist the oral experimental infection when the causative agent was introduced in the form of 20 ml broth culture or when the environment was contaminated with it. The Salmonella abortus ovis infection was found to be transmitted from infected rams to normal ewes and vice versa, chiefly through sexual route.
